1 Application filed September 25, 1911. Serial No. 651,260.

To all whom it may concern:

' Be it known that I, WILLIAM F. DEISTER, residing at Fort \Vayne, in the county of 'Allen and State of-Indiana, a citizen of the United States, have invented or discovered certainnew and useful Improvements in ment the following is a specification.

The invention described herein relates to certain improvements in slimeconcentrators, and has for its object a construction and combination of elements whereby the shifting of the table from feed to washing position and back to feed position, is effected automatically.

It is also an object of the invention to provide for the automatic movement of the table in accordance with the richness of the material treated. v

A further object of the invention is the utilization of the water employed in shift-,

ing the table, to remove the values, etc. deposited thereon.

The invention is hereinafter more fully described and claimed.

In the accompanying a part of this specification Figures 1 and 2 are side elevations of a slime concentrator uembodying my improvements, Fig. 1 showr by straps 8 arranged ing the apparatus in feed position and Fig. 2 showing the same in washing position; Fig. 3 is a top plan view; Figs. 41 and 5 are views similar to Fig. 1 illustrating modifications in the table shifting means and Fig. 6 is a side elevation illustrating a further modification of my improvement.

In the practice of my invention it is preferred to employ tables, each of which preferably consists of a series of decks 2, constructed and pivotally mounted described and claimed in an application Serial No.- 632,74- 3 filed by me June 12, 1911. As set forth in said application the several decks are pivotally supported about midway of their length on shafts 5 which are mounted .on posts or columns 6. The decks forming a table are connected so as to move in unison adjacent to the ends of the decks. Suitable means as boxes 12 having fan shaped directing trays 13 are arranged at one end of the table for feeding the material onto the decks, which when in feed position incline downwardly at a suitable angle from the trays. Pipes 17 having perforations or nozzles are arranged across the ends of the decks in suitable relation of which improvedrawings forming the pipe 20 to the upper surfaces thereof to effect a washing off-of deposits. These pipes are connected by flexible tubes 19 to a water supply pipe 20 provided witha controlling valve 21, adapted to as the table moves to and from washing position, as fully set tion referred to. described and shown in said application the table is shifted from feeding position to washing position and back to feeding position by'a motor driven mechanism and consequently without any regard to the richness of the materials treated. In order to avoid the use of such motor driven mechanism, the first cost of which is considerable as is also the cost of operation and maintenance, a natural force as gravity is employed for efiec-ting the desired movements of the table.

In the construction shown in Figs. 1, 2 and 3 one or moretanks or receptacles 35 are secured to the table at one side of the pivotal point and preferably closely adjacent to one end, thereby permitting of the employment of comparatively small tanks. The table should be so constructed and mounted that the end opposite that onto which the material is fed, will have a considerable preponderance of weight in order be opened and closed 4 that the table may be held in feed position 1 a suhicient length of time for the separation of the values. Suitable means are provided for discharging a liquid as water into the tank or receptacle. shown the tank 35 is connected bya flexible pipe 36 to a storage tank 37 secured at a suitable height to the post 6. For charging this tank a branch pipe 38 is attached to 35 is regulated by a valve 39 in the branch pipe. This valve during the discharge of liquid from the, counter-balancing tank 35,

During such feed the liquid will be discharged from the tanks until such time that the weight of they tables plus the accumulated deposits thereon will become sufficientto overcome the weight of the opposite end of the table. During theflushing period the 1t reaches Washing position the stem of valve 42 strikes a suitable abutment and the valve is shifted against the tension of its closing spring to open position, thereby permitting of the escape of the counter-balancing liquid from the tank 35..
